You've hit on a good point the Russian Front has always been very popular amongst wargamers, and it may pull a bunch of folks in. In fact, it may be the most popular front for WWII wargamers.
Personally, it's never been a favorite of mine, but that's just me. I've always enjoyed the Western Front the most, with Africa and the Med being second. Even though the Russian Front isn't my favorite, I'm excited about playing the Reds, and taunting my opponent with my best Dolph Lundgren, Russian-accented "I must break you."
I hope FotB knocks it out of the park for TOI. If the worst happens, though, I'm certain a small group of enthusiastic fans could work something out with FFG to carry on.
Dadgummit now you got me thinking about doing another issue of WOS, but I've got so many other irons in the fire…
